Initiative sets new sustainability benchmark for automotive industry
SUZHOU, China, Oct. 1 2025 – PPG (NYSE: PPG) today announced the launch of a cleaning solvent recycling project
in partnership with SAIC General Motors. The initiative, unveiled at the recent 2025 CARES Conference in Suzhou,
China, introduces a circular economy model for solvents used in automotive painting, enabling the reuse of up to 80%
by weight of waste solvents collected in OEM paint shops, marking a major step forward in sustainable automotive
manufacturing.
The project utilizes advanced distillation and purification technology to separate valuable components from waste solvents, repurposing them as raw materials for coatings or as reclaimed solvents (Image for illustrative purposes only).
The project utilizes advanced distillation and purification technology to separate valuable components from waste
solvents, repurposing them as raw materials for coatings or as reclaimed solvents. This closed-loop process offers a
more sustainable alternative to traditional solvent disposal methods, which typically involve incineration and
result in significant CO2 emissions. Compared to existing recycling techniques, the new method also drastically
reduces the volume of hazardous waste requiring disposal.
Through this joint initiative, PPG and SAIC General Motors will recycle more than 430 tons of waste solvents
annually, enhancing resource efficiency and environmental protection in the automotive sector. In recognition of
this achievement, in July the technology was awarded the 2025 RESPONSIBLE CARE® Sustainability Initiative Award
from the Association of International Chemical Manufacturers (AICM) in China.
“At SAIC General Motors, we’re committed to working hand-in-hand with our supplier partners to drive
innovation in sustainable solutions,” said Xu Xinghu, SGM painting process engineering manager. “Through
collaboration, we aim to unlock new possibilities and make meaningful progress toward our shared environmental
goals.”
“PPG continues to lead the industry with innovations such as precision application, 4-Wet sealants process
technology, expanded bake electrocoats and heavy-metal-free solutions,” said Tony Gu, PPG product engineering
director, Automotive Coatings Asia. “These technologies help automakers reduce carbon emissions, minimize
waste and improve efficiency while meeting stringent environmental standards. By collaborating with partners across
the value chain. PPG is accelerating the transition to a circular economy, driving the future of mobility toward
greater sustainability.”
